I had porridge made with water (yuk) with a few summer fruits in for breakfast.
I felt light headed as soon as i stood up after sitting for ten mins. Ive felt like this in the past before i was diagnosed and i used to just buy a bar of chocolate and i was ok.
Which is what the body does with low bgs, from my experience.
Low bgs on too much meds can be tweaked before blood pressure tablets need tweaking. Everyone experiences minor low or high blood pressure, that's normal. Its when its a permanent high or low med changes need considering by a medic. Not us.
